City Size

The size of a city impacts the airport build cost, the number of jobs that will be available when the jobs list refreshes, and the number of people or cargo units that can be in layover at any time at an airport. City sizes range from 0.0M to 10.0M people.

The general formula for build cost is , where the population is in millions.

Airport Size & Upgrades

Airports are divided into three sizes based on the population of the underlying city. In the "Airport Info" screen these are referred to as "Class 1", "Class 2", and "Class 3". The Class of an airport indictates what planes can fly into it. A Class 1 airport () will only allow Class 1 airplanes to land. A Class 2 () airport allows Class 1 and Class 2 planes to land, and Class 3 () airports allow all planes to land. You cannot change an airport's Class.

Airports can be upgraded to add more jobs & layover slots for a certain cost. All airports start at "Upgrade 1" and can be upgraded further using coins. Upgrading an airport will not change the airport's Class.

Advertising

Airports can be advertised for a certian cost to increase demand in that city for 8 hours. This will, of course, bring more people to that airport.

Formulae

There are 3 main formulae for airports: Opening Cost, Upgrade Cost, and Closing Value. (NB: In game, populations are given in millions to 2 decimal places, whereas the formula requires the 3 decimal places)
